Description of problem:
Internal compiler error building double.cc
Version-Release number of selected component (if applicable):
Steps to Reproduce:
Build jikes from src.rpm. (first, it is necessarry to comment out NAN in
double.h - because it is defined in gcc's standard headers)
Can you please write here the g++ options used to reproduce it, rerun it
with -save-temps in addition to that and attach here double.ii?
The command line is:
i686-redhat-linux-g++ -DHAVE_CONFIG_H -I. -I. -I. -O2 -march=i686 -c -o
double.o `test -f double.cpp || echo './'`double.cpp

The temporary file
The primary problem is that g++ 3.x defines _GNU_SOURCE unconditionally for C++,
so e.g. <bits/nan.h> gets included, which colides with Jikes' NAN enum.
Either Jikes should #undef NAN after including all headers, or choose another
name for NAN in the enum.
But of course, compiler shouldn't segfault. Looking into it.
